Ford Canada had their own way of marking blocks. Ford US would use stamps until they started changing paint colors for different blocks like the 99A. I guess they felt that was good enough for ID purposes during manufacture.

And...there were 2 81 24 stud blocks, short crank 1938 only (same crank as the last 21 studs) and late '38---41 or so with the long crank and bigger bearings. Long crank was because of crank mounted fan.
